Why would this rank them so high though? Does the googlebot actually follow the http-equiv="refresh". If so, would changing http://stackoverflow.com to say http://dell.com make them rank #1 for searching for dell as well?
That sounds too easy. Also, if doioig.gov redirects to stackoverflow.com that just makes doioig.gov an alias for Stack Overflow. An alias shouldn't rank higher than the real thing.
